What is MPLS
•MPLS stands for “Multi-Protocol Label Switching”.
•MPLS is best summarized as a “Layer 2.5 networking protocol”.
•MPLS combines layer 2 switching technology and layer3 routing technology so that it becomes the bestnetwork solution in solving speed, scalability, QOS(Quality of Service), and traffic engineering problems.

Label Switching
MPLS does “label switching” instead:
The router applies a “label” based on this information.
Future routers use the label to route the traffic
At the final destination router the label is removed.
And the packet is delivered via normal IP routing.

MPLS Operation
• At ingress LSR (Label Switch Router) of an MPLS domain, an MPLS header is inserted to a packet before the packet is forwarded
• At subsequent LSRs• The label is used as an index into a forwarding table that
specifies the next hop and a new label. • The old label is replaced with the new label, and the
packet is forwarded to the next hop.
• Egress LSR strips the label and forwards the packet to final destination based on the IP packet header

VPLS
• VPLS defines an architecture allows MPLS networks offer Layer 2 multipoint Ethernet Services
• SP emulates an IEEE Ethernet bridge network (virtual)

LDP (Label Distribution Protocol)
Label Distribution Protocol ‒ LDP works between adjacent/non-adjacent peers
LDP sessions are established between peers
LDP messages sent in the form of TLVs (Type, Length, Value)

Label Space Of LDP
LSRs establish one LDP session per label space. Per-platform label space requires only one LDP session,even if there are multiple parallel links between a pairof LSRs.
Per-platform label space is announced by setting thelabel space ID
